A digital loudspeaker is one that does not contain any form of embedded digital to analogue converter. From a consideration of the mathematical operations describing the digital to analogue conversion process in a digital loudspeaker, it is concluded that n identical analogue filters (where n is the number of bits) separately filtering each bit driver offers a practical alternative to digital signal processing. The implementation of a multiple driver multiple voice coil digital loudspeaker is described. The effect of component tolerances in the crossover and compatibility with the requirements of current drive are evaluated. The interactions between the motion emf, driving current and mutual coupling emfs are considered. It is concluded that this method of crossover implementation is both viable and achievable.
